METHOD FOR USE OF CITRACONIC ANIDRIDE, POLYIMIDE OLIGOMERS WITH TWO STAGE HEALING, SOLUTION, LOW-VOLUME BOOSTED, HIGH-TEMPERATURE COMPOSITE, AND ADHESIVES

摘要

2-stage cured polyimide oligomers. The present invention relates to a method of using citraconic anhydride and itaconic anhydride as addition curing end caps in reactions for formation of polyamic acid oligomers and polyimide oligomers. High temperature prepregs and adhesives manufactured from the resulting oligomers as well as high temperature low void composites made from prepregs are also provided.
